Be it known that I, ConNELrUsG. HAs'rmos, a citizen of the United States, and a resident of the city of Glendale, in the county of Los Angeles and State of-Cali? panying drawings} andto the numerals of reference marked thereon, v which form a part of this specification."

This invention relates to a machine adapted for use particularly in the construction of tunnels, conduits, and the llke, al-

though of course well adapted for other.

similar purposes, and more particularly adapted for use. with tunneling shields such as set forth in my co-pending application for tunneling shields filed November 19th, 1914f, SerialNo. 872,921. By this in-. vention rapid construction of a tunnelfor conduit is assured, inasmuch as the building blocks may be laid in built UP relation withthe utmost facility and maybe held temporarily in position by the machine until the interlocking means provided for the purpose are fitted with the building blocks to hold the same properly, disposed until the grouting or surroundinglayers of {con t through the forward end of the tunnel uncrete areblown therearound'. V

' It is an object therefore of this invention to construct an erecting machine with a movable platform or' carriage provided with construct an erecting machine for use in building up the lining of a tunnel or conduit from the interior thereof, the-machine acting to grip and'elevatethe blocks to any desired position. p

It is also an object. of this invention to construct a machinefor placing, the build ing blocks comprising the liningof'a tunnel in built up relation, said machine movable upon a carriage or platform advanced from time to time as successive rows or layers of blocks are laid in'position, upon Specification of Letters Patent.

It s-furthermore an ob ect of this in- .VGIltlOIl to construct an erecting machine comprising a traveling platforrnwith pivotally mounted telescoping extensible carry ing arm mounted thereon and provided'with jaws adapted to grip and pick up a block to be swung by said arm to the desired position and projected thereinto so thata series 'of said blocks may be laid one upon another to forma complete row or additional layer in the tunnel lining.

It is also an ob'ect ofthis invention to construct van erecting machine adapted toi travel within atunnel or conduit, following closely upon a tunnelingshield to lay a row of blocks in built up relation within the flexible apron at the rear end of the shield prior to the successiveadvancements thereof.

Mounted in suitable bearings provided for the purpose parallel to the engine 24, is a longtubular shaft v27 provided with a worm wheel 28, meshing with the worm 26, and

leading into the end of said tubular shaftv 27, is an air supply pipe 29, connected to the reservoir 22.

A detachable wrench handle 20, is provided,adapted to be engaged. over the squared end of the bolt 18, p

Secured upon the forward end of the tubular shaft .27, the detail of connection of which is shown in Fig, 8, by means of a bracket 29?, is a long telescoping arm consisting of a tubular section 30, having fitted therein another tubular section 31, which inturn has fit ed therein anQther tubular sec a .tion 32. Communicating laterally through the endof the tubular shaft 27 ,is a pipe 33, which'isconnected through a four way valve 34, having a relief opening therein, to

branch pipes 35 and 36, respectively, oneleading into one end of the tubular-member;

30, and the. other leading into the middle portion thereofnear a partition37, therein.

Mounted within the tubular member 30, be-

is apiston 38, havinga piston rod '39, con. nected theretoextending slidably and "sealingly through said partition 37, and at its end threaded into the end ofvthe tubular member 31, so that Inovement'of the piston V a acts to extend or retract the tubular member 31, from or. into the tubular member 30.

provided within the tubular element 31,- at

A headfior closure 49 is provided in the end of. the tubular member 32, and has a' narrowed extension 50,-throu'gh which extends a small shaft 51, having squared ends to receive attached thereto lon lever or wrench. I Secureduaon said shaft 51 oneachz side :orthe narrowed extension 50, are eccentrics 52, and-pivoted at each side at, the outer end of said extension 50, are jaws 5,3, the gripping orcontact surfaces of which are roughened or serrated. Connected between each of said aws-53,- are a pair of toggle links 54, and connected to arm may engage with a. block inthe' inlaid channel 4, thereof, when said block is at any point within reach of the arm, though usually below the same and the valves 34 and 41, are then actuated to extend the arm carrying the block to place the block in position, after which an operator inserts the interlocln'ng rods, such as disclosed and described in my co-pending application for tunnel block and tunnel construction, filed October 18th,;1915, Serial No. 56,517.

The operation of extending the elements 4 31, from the element 30, is effected by adtended from the extended element 31, by"

adjusting the valve 41, such that air is adj ustment of the valve 34, such that air under pressure is admitted through the branch pipe35, behind the piston 38, thereby forcing the same along in its tubular cylinder 30, with the fluid in front of the piston expelled through the member 36, and through the outlet relief pipeiof the valve 34. If this extension of thetubular arm is insufficient,the tubular element 32, may be ex! mitted through the passage 44, behin'dthe piston 47, thereby driving the same for;

wardlyin the cylinder and the fluid in front of the piston is expelled through the pipe 43, and outwardly through the relief pipe in the four way valve 41. The retractive or telescoping movementsof the parts of the extensible arm are'effected by so adjusting the valves 34and'41, that the'air' under pres sure is admitted infront of the respective pistons 47 and 38, and the fluid within the respective-cylinders at the rear of the pistons, as said pistons move inwardly therein, is expel-led througlr the piping connections and-outwardly through the-relief oroutlet pipes of said respective valves 41 and 34. 0f coursethe telescoping z vrm' may be rotated any desireddegree by operation of the compressed jair engine 24, and the niggerhead 25, also operated thereby,may;bc utilized, bywinding a cable therearound, to

haul the carriage of the'ferecting machine forwardly or rearwardly within the tunnel, as. desired. (However, when the carriage has been 'moved to a desired-(point with n the tunnel, the clamping plates-1 7; are swung downwardly to engage the T-bar rings 5,

and the adjusting bolts 18, are thenactuated by the cranks 20,, provided for the purpose, to tightentthe clampsupon the T-bar rings and thus hold, the carriage substantially in a fixed position. Asthe tunnel work pro-, gresses, additionalbrackets or frames 6, are placed in position by clamping: the same upon the sectional T bars 5, thus providing a support with roller'sthereon on which the carriage may be moved from time'to time as the work requires. As already pointed out, the layer of blocks built up within the tunnel by the telscoping arms, is that layer atthe end and within the apron of'the' t-unnel shield 2, and with theparts'shown in i the position illustrated in Fig. 2, the carriage and associated mechanisms are ready to be advanced forwardly in the tunnel, but

the rows oflblocks immediately'behind the apron of the tunnel have been omitted for clearness.
